A case of non-involuting congenital haemangioma with multiple epidermal cysts.

Abstract

While infantile haemangiomas are the most common tumours of childhood, rare congenital haemangiomas grow to maximum size at birth and then spontaneously and rapidly regress (rapidly involuting congenital haemangiomas). However, certain congenital haemangiomas, described recently as 'non-involuting congenital haemangiomas', evolve differently and do not regress. There are several options regarding the treatment of infantile haemangiomas, but few reports have addressed the treatments of non-involuting congenital haemangiomas, though a small number have recommended surgical excision. However, the treatments of non-involuting congenital haemangiomas with multiple epidermal cysts have not been investigated. Epidermal cysts can cause recurrent infection, and we suspect that recurrent ulceration might cause the implantation of epidermal cells into the dermis, and result in the development of multiple epidermal cysts. Currently, epidermal cysts are treated by surgical excision, which should reduce complication rates. Herein, we report our experience of treating repeatedly infected non-involuting congenital haemangioma with multiple epidermal cysts.
